DETAILED DESCRIPTION

Exemplary embodiments will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a front side of a digital image processing apparatus, according to an embodiment. FIG. 2 is a view showing a rear side of the digital camera 10 shown in FIG. 1 according to an embodiment.

Referring to FIGS. 1 and 2, the digital image processing apparatus may be a digital camera 10 that includes a body 10 a, and a lens module 100.

The body 10 a may be a main body of the digital camera 10, and may include various components, which are necessary for operating the digital camera 10 disposed on inner and/or outer sides of the body 10 a.

The lens module 100 may be mounted on the body 10 a. The lens module 100 may be a replaceable lens module which is mounted removably from the body 10 a. The lens module 100 may alternatively be a fixed lens rather than a replaceable lens. However, the lens module 100 is not limited to the above examples.

The lens module 100 may include a lens barrel 100 a, an adjustment unit (or adjustment ring) 110, and a selection unit (or selection button) 120. In the lens barrel 100 a, at least one lens may be installed to move in an optical-axis direction. The adjustment ring 110 and/or the selection button 120 may be installed on or in the lens barrel 100 a.

In some embodiments, the adjustment unit 110 may be an adjustment ring 110, which allows adjustment of a setting value of a selection item selected by manipulating the adjustment unit. The adjustment ring 110 may change or adjust a setting value of a particular setting item by being manipulated. The adjustment ring 110 may be mounted on or in the lens module 100 to allow a user to easily change and/or adjust a setting value.

In some embodiments, the selection unit 120 may be a selection button 120 for selecting a selection item to be set from among a plurality of setting items. The selection button 120 may, by being manipulated, call an i-Function (iFn) menu or change a setting item to be set.

In the embodiment shown, both the adjustment ring 110 and the selection button 120 are installed in the lens module 100. However, the adjustment ring 110 and/or the selection button 120 may also be installed on or in the body 10 a, and are not limited to the foregoing example.

When the lens module 100 is a replaceable lens module, a focus, a zoom, and an aperture may be adjusted in the lens module 100; and therefore, the user often manipulates the lens module 100. A physical user interface (PUI) or a separate manipulation ring for manipulating the focus, the zoom, and the aperture may be used as a selection unit 120 and/or an adjustment unit 110.

Accordingly, by using the selection unit 120 and/or the adjustment unit 110, the user may easily perform a setting operation necessary for a photographing operation of the camera 10 and/or other operations.

For the photographing operation of the digital camera 10 or other various operations, setting values of setting items may be set or changed. Upon manipulation of the adjustment ring 110, a setting value of a setting item designated to correspond to the manipulation may be set or changed.

The setting item set by the manipulation of the adjustment ring 110 may be at least one of a photographing mode, white balance, exposure correction, flash radiation intensity adjustment, sensitivity adjustment, digital zoom, and focusing region change.

When a zoom ratio of digital zoom is designated as the setting item to be set by manipulation of the adjustment ring 110, the angle of view may be changed by using digital zoom, as in the case of a single-focus lens.

In the embodiment shown, the selection button 120 is used as the selection unit 120. However, the selection unit 120 may be at least one of a button, a sliding switch, and a rotational selector switch, and is not limited to the foregoing examples.

The setting item to be set may be changed by a selection operation of the selection unit 120. For example, setting items to be set by manipulation of the adjustment ring 110 are designated and an order thereof is designated, and a setting item to be set by manipulation of the adjustment ring 110 may be changed according to the number of times the selection unit 120 is selected.

The selection unit 120 may be a selection ring 120 a which is installed as a ring type device on the lens barrel 100 a. The selection ring 120 a may be rotated with respect to the lens barrel 100 a or may be slid in a longitudinal direction of the lens barrel 100 a.

In another embodiment, the selection unit 120 may be a rotational selector switch of the same type as the mode dial 13 installed in the body 10 a. In still another embodiment, the selection unit 120 may be a menu system displayed on a display device 15 (shown in FIG. 2) installed in the body 10 a.

The adjustment ring 110 may be installed as a ring type device which encloses at least an outer part of the lens barrel 100 a, preferably disposed around an outer circumferential surface of the lens barrel 100 a. The adjustment ring 110 may be installed to be rotatable with respect to the lens barrel 100 a. In this case, the adjustment ring 110 may be rotated with respect to the lens barrel 100 a. The adjustment ring 110 may have a structure capable of rotating around a particular section or infinitely.

In another embodiment, as shown in FIG. 5, the adjustment ring 110 a may be installed so as to be slidable with respect to the lens barrel 100 a in the optical-axis direction of the lens. In this case, the adjustment ring 110 may be slid forward or backward in the optical-axis direction with respect to the lens barrel 100 a.

However, embodiments are not limited to the foregoing examples, and the adjustment ring 110 a may be installed to be rotated and slid with respect to the lens barrel 100 a. In such an embodiment, the adjustment ring 110 a can be rotated and/or slid with respect to the lens barrel 100 a. As such, by allowing the adjustment ring 110 a to be manipulated in various ways, user convenience in setting a setting value by using the adjustment ring 110 a can be improved.

In the digital camera 10, various types of lens module 100 as shown in FIGS. 4, 5, 6, 11, or 12 as well as the lens module 100 shown in FIG. 1 may be replaced and mounted.

The lens module 100 according to the embodiment shown in FIG. 1 includes a single adjustment ring 110. The adjustment ring 110 may be an aperture adjustment ring for adjusting an aperture by manipulation thereof, a zoom adjustment ring for adjusting zoom by manipulation thereof, or a focus adjustment ring for adjusting focus by manipulation thereof.

The lens module 100 includes at least one of the focus adjustment ring, the zoom adjustment ring, and the aperture adjustment ring, and one or more adjustment rings selected by selection of the selection button 120 may be the adjustment ring 110 of the digital camera 10 according to an embodiment. In this way, a setting value to be set can be easily set or changed without a need to mount an additional apparatus and sensor structure for a separate adjustment ring.

To this end, a setting item to be set by the adjustment ring 110 is previously designated and whether to set a setting value of the previously designated setting item, focus, zoom, or aperture by manipulation of the adjustment ring 110 is selected by selection of the selection button 120.

In an embodiment shown in FIG. 6, a lens module 100′ includes an aperture adjustment ring 111, a zoom adjustment ring 112, and a focus adjustment ring 113 which are mounted on a lens barrel 100 a′.

At least one of the aperture adjustment ring 111 for adjusting an aperture by manipulation thereof, the zoom adjustment ring 112 for adjusting zoom by manipulation thereof, and the focus adjustment ring 113 for adjusting focus by manipulation thereof may serve as the adjustment ring 110.

By selection of the selection button 120 or selection of another separately provided selector button (for example, button 20 of FIG. 2), at least one of the aperture adjustment ring 111, the zoom adjustment ring 112, and the focus adjustment ring 113 may be selected as the adjustment ring 110.

Meanwhile, a shutter-release button 12 and a mode dial 13 may be provided on an outer side of the body 10 a of the digital camera 10. A direction button 16, a menu-OK button 17, and a display panel 15 may be provided on a rear side of the digital camera 10.

The shutter-release button 12 may open or close a shutter to expose an imaging device (for example, a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS)) to light for a predetermined time. The mode dial 13 is used to input a photographing mode selection.

In the body 10 a of the digital camera 10, various modes may be selected and inputted through the mode dial 13. The various modes can include an AUTO (automatic photographing) mode for minimizing user setting and quickly and conveniently capturing an image according to the purpose of use, a SCENE mode for simply setting optical camera settings according to a photographing condition or a state of an object, an EFFECT mode for giving a special effect to image capturing such as continuous capturing and scene capturing, and an A/S/M mode for manually setting various functions including an aperture and a shutter speed for a photographing operation.

The various modes may further include an additional mode, e.g., an intelligent function mode to allow at least one of the focus adjustment ring 113, the zoom adjustment ring 112, and the aperture adjustment ring 111 included in the lens module 100 to function as the adjustment ring 110 according to an embodiment. In this case, when the mode dial 13 provides the intelligent function mode and the intelligent function mode is selected, a corresponding set adjustment ring 111, 112, or 113 may operate as the adjustment ring 110.

The direction button 16 may include a total of four buttons including an up button, a down button, a left button, and a right button. Through operations of the direction button 16 and the menu-OK button 17, various menus associated with operations of the digital image processing apparatus, such as the digital camera 10, may be executed and displayed on the display panel 15.

A menu system is displayed on a display device such as the display panel 15, and operates by manipulation of a touch screen and/or the direction button 16 and the menu-OK button 17. In this case, setting items that can be set by manipulation of the adjustment ring 110 are designated and an order thereof may be designated by the menu system.

The menu system may be the selection unit 120 according to an embodiment which changes a setting item to be set, by selection thereof.

In the body 10 a of the digital camera 10, a manipulation switch 11 for moving the lens forward or backward may be provided. The manipulation switch 11 may include a forward manipulation switch 11 a and a backward manipulation switch 11 b.

The lens module 100 may operate to move the lens forward by manipulation of the forward manipulation switch 11 a. The lens module 100 may also operate to move the lens backward by manipulation of the backward manipulation switch 11 b.

In the embodiment shown in FIG. 1, the focus adjustment ring may be used as the adjustment ring 110. In this case, by selection of the selection unit 120, the adjustment ring 110 may function as the focus adjustment ring or may be used as the adjustment ring 110 for setting a setting value for a setting item designated according to an embodiment.

When the adjustment ring 110 is used as the focus adjustment ring, upon manipulation of the adjustment ring 110, a focus lens mounted in the lens barrel 100 a is moved forward or backward in the optical-axis direction to adjust focus. In particular, in an auto focusing mode where the focus adjustment ring is not used for focus control input, the focus adjustment ring may be used instead as the adjustment ring 110 without separate selection of the selection unit 120. In a manual focusing mode, the focus adjustment ring may be used for focus adjustment.

The display panel 15 may be an image display element such as a liquid crystal display (LCD). The display panel 15 may be included in a display unit where an input image is displayed as a live view or a stored image is reproduced and displayed. A control apparatus 200 shown in FIG. 3 may be mounted in an inner side and/or an outer side of the body 10 a of the digital camera 10.

An embodiment of the digital image processing apparatus can be applied to a digital camera and an apparatus and method for controlling the same disclosed in U.S. Patent Application Pub. No. 2004/0130650 to the present applicant (entitled “Method of Automatically Focusing Using Quadratic Function in Camera”). The digital camera and the apparatus and method for controlling the same disclosed in the aforementioned U.S. Patent Application Pub. No. 2004/0130650 is incorporated herein in its entirety by reference, and a description thereof will not be provided.

FIG. 3 is a block diagram of the control apparatus 200 of the digital image processing apparatus according to an embodiment. The control apparatus 200 may be mounted in an inner side of the digital camera 10 shown in FIG. 1.

Referring to FIG. 3, an optical system (OPS) 221 may include a lens portion and a filter portion to optically process light incident from an object. The lens portion of the OPS 221 may include a zoom lens, a focus lens, and a compensation lens. Once a user presses a wide-angle-zoom button W or a telephoto-zoom button T included in a user input unit 217, a corresponding signal is input to a microcontroller 212.

In accordance with the microcontroller 212 and the user input unit 217, a zoom motor M_(z) can be driven to move the zoom lens. That is, when the wide-angle-zoom button W is pressed, a focal length of the zoom lens is reduced, thus increasing the angle of view; and when the telephoto-zoom button T is pressed, the focal length of the zoom lens is increased, thus reducing the angle of view.

In the auto focusing mode, a main controller embedded in a digital signal processor (DSP) 207 can control an optical driving unit 210 through the microcontroller 212 and thus drives a focus motor M_(F). In other words, by driving the focus motor M_(F), the focus lens can be moved to a focus position where the clearest picture can be obtained, thus performing automatic focus adjustment.

The compensation lens may not be separately driven because it compensates for an overall refractive index. An aperture adjustment motor M_(A) can be used to drive an aperture.

The filter portion of the OPS 221 may include an optical low pass filter and an infra-red cut filter. The optical low pass filter can cancel optical noise of a high-frequency component. The infra-red cut filter can cut an infra-red component of incident light.

An optical-electronic converter (OEC) 222 may include an imaging device such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The OEC 222 can convert light from the OPS 221 into an electric analog signal.

An analog-to-digital converter (ADC) may include a correlation double sampler and analog-to-digital converter (CDS-ADC) 201. The ADC can process an analog signal from the OEC 222 to cancel high-frequency noise from the analog signal and/or to adjust the amplitude of the analog signal, and can then convert the analog signal into a digital signal. The DSP 207 can control a timing circuit 202 to control operations of the OEC 222 and the CDS-ADC 201.

The OPS 221, the OEC 222, and the CDS-ADC 201 may be included in an image input unit for receiving an input image according to an embodiment.

A real-time clock (RTC) 203 can provide time information to the DSP 207. The DSP 207 can process the digital signal provided from the CDS-ADC 201 to generate a digital image signal classified with luminance (Y) and color (R, G, B) or chroma, brightness, and color (R, G, B).

A light emission portion 216 driven by the microcontroller 212 under the control of the main controller embedded in the DSP 207 may include a self-timer lamp, an auto-focusing lamp, a mode indication lamp, and a flash standby mode.

A dynamic random access memory (DRAM) 204 can temporarily store the digital image signal from the DSP 207. An electrically erasable and programmable read only memory (EEPROM) 205 can store algorithms and setting data, such as a booting program and a key input program necessary for an operation of the DSP 207. A user's memory card may be removable from a memory card interface (MCI) 206.

The digital image signal from the DSP 207 can be input to a display panel driving unit 214, and thus the image can be displayed on a display panel 215.

The display panel 215 and the display panel driving unit 214 for driving the display panel 215 may be included in a display unit according an embodiment. An input image may be displayed as a live view or a stored image may be reproduced and displayed on the display unit.

The digital image signal from the DSP 207 may be transmitted via serial communication through a universal serial bus (USB) connection unit 231 a or an RS232C interface 208 and a connection unit 231 b thereof, and may be transmitted as a video signal through a video filter 209 and a video output unit 231 c. The DSP 207 may have a microcontroller embedded therein.

An audio processor 213 outputs an audio signal from a microphone 218 to the DSP 207 or a speaker 219, and outputs an audio signal from the DSP 207 to the speaker 219. A flash controller 211 controls an operation of a flash 220. The flash controller 211 may be controlled by a control signal that is output from the microcontroller 212.

FIGS. 7 and 8 schematically show embodiments of the i-Function menu displayed on the display panel 15 of the digital camera 10 shown in FIG. 2.

Referring to FIGS. 7 and 8, the display panel 15 can display display screens 70 and 80 which show an image and/or various settings or operation statuses. The display screens 70 and 80 may include selection regions 72 and 82, respectively, and adjustment regions 71 and 81, respectively.

The selection regions 72 and 82 may show at least one setting item. The adjustment regions 71 and 81 may show a setting value which is currently set for at least one displayed setting item, together with candidate setting values that can be set for the at least one displayed setting item.

In other words, at least one setting item and an adjustment status of a setting value for a particular setting item can be displayed on the display screens 70 and 80. Thus, the user can see setting items that can be set and a setting status of a setting item to be set at a glance on a single screen. As such, the apparatus for processing a digital image according to an embodiment can improve user convenience in a menu setting operation through the i-Function menu.

Menus displayed on the selection regions 72 and 82 and the adjustment regions 71 and 81 may be controlled by the selection unit 120, e.g., the selection button 120, and the adjustment unit 110, e.g., the adjustment ring 110. Thus, by interworking the physical user interface (PUI) and a graphic user interface (GUI), user convenience in a function setting operation can be improved.

Selection bars 74 and 84 may be displayed on the selection regions 72 and 82, respectively. The selection bars 74 and 84 may be displayed such that designated setting items are disposed in sequence according to a set display order on the selection regions 72 and 82.

Adjustment bars 73 and 83 may be displayed on the adjustment regions 71 and 81. The adjustment bars 73 and 83 may be displayed for a selection item designated by default or selected from among the display items displayed on the selection bars 74 and 84, such that a currently set setting value and candidate setting values that can be set may be disposed together in sequence on the adjustment regions 71 and 81.

The selection item may be a setting item designated by default upon call of an i-Function menu among candidate items. In another embodiment, the selection item may have been selected from among the display items displayed on the selection bar 74 or 84 by manipulation of the selection button 120 or the selection ring 120.

To this end, candidate items that can be displayed on the selection bar 74 or 84 may be designated, and a predetermined number of display items among the candidate items may be displayed on the selection bar 74 or 84. The selection item among the display items may be displayed differently from the other display items, thereby allowing the user to easily recognize the display item for which a setting value is displayed on the adjustment bar 73 or 83.

FIG. 7 shows an embodiment of an i-Function menu where aperture F is a selection item. Thus, aperture F may be the selection item and be displayed differently from the other display items.

The selection bar 74 may display focus auto (MF, CAF), aperture F, shutter speed S, exposure EV, sensitivity ISO, white balance WB, and zoom iZoom as display items. In the embodiment shown in FIG. 7, the aperture F is selected as a selection item, and the selection item may be displayed distinguishably by being dashed or colored differently.

FIG. 8 shows an embodiment of an i-Function menu where manual focus MF is a selection item. Thus, the manual focus MF may be the selection item and be displayed differently from the other display items.

The selection bar 84 may display focus (MF, CAF), aperture F, shutter speed S, exposure EV, sensitivity ISO, white balance WB, and zoom iZoom as display items. In the embodiment shown in FIG. 8, the manual focus is selected as a selection item, and the selection item may be displayed distinguishably by being dashed or colored differently.

When the number of display items displayed on the selection bar 74 or 84 is less than the number of candidate items, a configuration of display items may be changed with a change in selection items.

Setting items and current setting values therefor may be displayed together on the selection bar 74 or 84. For example, as shown in FIG. 7, aperture F and a setting value of 4 for the same, shutter speed S and a setting value of 4000 for the same, sensitivity ISO and a setting value of 3200 for the same, white balance WB and a setting value of sunlight for the same, and zoom iZoom and a setting value of x1 for the same may be displayed together on the selection bar 74.

On the adjustment bar 73 or 83, a setting range of candidate setting values for a selection item may be displayed according to a set order. A current setting value may also be displayed together with the setting range on the adjustment bars 73 and 83.

The setting range may be displayed in order of magnitude of candidate setting values for a setting item having a setting value distinguished by its magnitude. On the adjustment bar 73 or 83, a setting range of candidate setting values for a selection item may be displayed in order of magnitude.

The setting range of candidate setting values for a selection item may be displayed according to magnitude from left to right or from right to left. Thus, the user can intuitively recognize the setting range and the current setting value.

The setting range may be displayed as an image or a character on the adjustment bar 73 or 83. A lower limit, an upper limit, and a current setting value of the setting range may be displayed as characters on the adjustment bar 73 or 83. On the adjustment bar 73 or 83, the setting range may be displayed in the shape of a graduated ruler or a bar graph.

In the embodiment shown in FIG. 7, the aperture F is selected as a selection item, a setting range for the aperture F is displayed in the shape of a graduated ruler with a lower limit of 2.8 and an upper limit of 16 on the adjustment bar 73. A current setting value of 4 may be displayed in a position corresponding to the current setting value within the entire setting range displayed as a graduated ruler on the adjustment bar 73.

In the embodiment shown in FIG. 8, the manual focus MF is selected as a selection item and a setting range for the manual focus MF is displayed in the shape of a bar graph with a lower limit of near and an upper limit of far on the adjustment bar 83. A current setting value may be displayed in a position corresponding to the current setting value within the entire setting range displayed as a bar graph on the adjustment bar 83.

In this case, by manipulation of the selection button 120, the selection item may be activated while moving from left to right or from right to left on the selection bar 74 or 84. As the selection item is changed, a setting range and a setting value for the activated selection item may be automatically changed to range and values corresponding to the changed selection item. The change of the selection item may be made according to the number of times the selection button 120 is pressed.

By manipulation of the adjustment ring 110, the current setting value may be changed from left to right or from right to left on the adjustment bar 73 or 83. The current setting value may be applied as a setting value for a selection item by manipulation of a particular button, for example, the menu-OK button 17, thus changing the setting value for the selection item.

According to a direction of rotation of the adjustment ring 110, the setting value for the selection item may be increased or decreased. For example, if the adjustment ring 110 is rotated to the left, the current setting value may be decreased on the adjustment bar 73 or 83; if the adjustment ring 110 is rotated to the right, the current setting value may be increased on the adjustment bar 73 or 83.

In another embodiment, when a setting value for a setting item is changed, the changed setting value may be reflected in real time. In other words, upon manipulation of the adjustment ring 110, the current setting value of the selection item is changed on the adjustment bar 73 or 83 and the setting value of the selection item is reflected and changed in real time, such that input of an input image or an operation of the camera 10 may be performed with the changed setting value.

When a setting value of a setting item is changed, a setting value of another setting item may also be changed in connection with the setting value of the setting item. For example, for setting items including aperture, shutter speed, and exposure, when a setting value for one of these setting items is changed, a setting value of another setting item may also be changed at the same time.

In this case, when the setting value for the setting item is changed, an input image may be inputted based on the changed setting value, and the input image can be displayed as a live view on the display panel 15.

A change of the setting value associated with a photographing operation may be reflected in real time, and an input image may be input based on the changed setting value. The input image based on the changed setting value may be displayed as a live view on the display panel 15. Setting items changed in real time in association with a photographing operation may include aperture, shutter speed, and exposure.

By selection of a menu setting or a designated button (for example, button 20 of FIG. 2), an i-Function menu may be called and displayed on the display screen 70 or 80. In this case, once the i-Function menu is called, the selection bar 74 or 84 may be displayed on the selection region 72 or 82 and the adjustment bar 73 or 83 may be displayed on the adjustment region 71 or 81.

For example, by pressing the selection button 120 corresponding to the selection unit during operation of the camera, the i-Function menu may be called. Thus, a designated selection item is activated and the adjustment bar 73 or 83 for the selection item are displayed to allow the user to adjust a setting value for the selection item.

In another embodiment, when a particular menu is called or a particular button assigned to the particular menu is pressed during an on-state of the iFn, the i-Function menu may be displayed on the display screen 70 or 80. In another embodiment, if the adjustment unit, for example, the adjustment ring 110 is actuated during an on-state of a set function, e.g., the iFn, the selection bar 74 or 84 can be displayed on the selection region 72 or 82 and the adjustment bar 73 or 83 can be displayed on the adjustment region 71 or 81, such that the i-Function menu can be called.

Depending on a function and/or a feature set by a setting item, a scheme for matching the PUI and the GUI may change. Thus, by intuitively connecting the PUI and the GUI, function setting by the user can be facilitated.

In other words, if a setting value set by a setting item is independent, rather than continuous or homogeneous, it may be changed by a discontinuous type manipulation unit. If a setting value set by a setting item is continuous or homogeneous, it may be changed by a continuous type manipulation.

In this regard, white balance WB may be a setting item having a discontinuous setting value, and aperture F, shutter speed S, and zoom iZoom may be setting items having continuous setting values.

The discontinuous-type manipulation unit may be at least one of a button, a sliding switch, a rotation ring, and a rotation selector switch. The continuous-type manipulation unit may be a ring type manipulation unit. The ring-type manipulation unit may be rotated with respect to the lens barrel 100 a or may be slid in the longitudinal direction of the lens barrel 100 a.

FIG. 9 shows an embodiment of a selection region 93 of an i-Function menu, which is displayed in a blank region 92 due to a difference in an aspect ratio between the display panel 15 and the imaging device. The aspect ratio of the display panel 15 may not be the same as that of the imaging device. In this case, when an input image inputted through the imaging device is displayed on the display panel 15 without changing the aspect ratio of the input image, a blank region 92 where no image is displayed may be generated on a display screen 90 of the display panel 15.

The entire display screen 90 may include an image region 91 where an image is displayed and the blank region 92 where no image is displayed. The blank region 92 may be a wasted region of the display screen 90. However, at least one of the selection region 93 and the adjustment region may be disposed on the blank region 92. In the embodiment shown in FIG. 9, the selection region 93 is disposed on the blank region 92.

Accordingly, the display screen 90 of the display panel 15 can be efficiently utilized.

In the embodiment shown in FIG. 10, a lower end portion of a display screen 101 displayed on the display panel 15 is used as an information display region 102.

That is, the lower end portion of the display screen 101 is used as the information display region 102 where a current setting status of a function necessary for a photographing operation or another operation of the camera may be shown to the user.

Once the i-Function menu is called, the information display region 102 can disappear and the selection bar 74 and the adjustment bar 73 as shown in FIG. 7 can be displayed on corresponding positions. In this case, in the i-Function menu, the simple passive information display region 102 may be used as an active information setting region with the selection bar 74 and the adjustment bar 73.

The information display region 102 may be the blank region 92 of FIG. 9. In this case, when a live view image is displayed on the display panel 15, currently set setting information may be displayed on the blank region 92. When a preset setting function, for example, the i-Function menu, is called, at least one of the selection region and the adjustment region may be displayed on the blank region.

FIGS. 11 and 12 illustrate embodiments of the i-Function menu in which the selection bar 74 or 84 and the adjustment bar 73 or 83 are disposed on the display screen 70 or 80 at positions corresponding to positions of the selection unit and then adjustment ring. Referring to FIGS. 11 and 12, the selection bar 74 or 84 and the adjustment bar 73 or 83 are disposed on the display screen 70 or 80 at positions corresponding to positions of the selection unit 120 and the adjustment ring 110.

That is, if the selection unit 110 is disposed behind the adjustment unit 120 with respect to the body 10 a, the selection bar 74 may be disposed under the adjustment bar 73 on the display screen. In another embodiment, if the selection unit 110 is disposed in front of the adjustment unit 120 with respect to the body 10 a, the selection bar 74 may be disposed above the adjustment bar 73 on the display screen.

Thus, by matching a position relation of the PUI and a position relation of the GUI, the user can set a setting function by intuitive manipulation.

FIG. 11 shows a position relationship between the selection bar 74 and the adjustment bar 73 when the selection unit 120 is the selection button 120 and the adjustment unit 110 is the adjustment ring 110 that is a rotational ring type. When the selection button 120 is disposed behind the adjustment ring 110, the selection bar 74 is disposed behind the adjustment bar 73 on the display screen.

FIG. 12 shows a position relationship between the selection bar 74 and the adjustment bar 73 when the selection unit 120 is a selection ring 120 a that is a rotational ring type and the adjustment unit 110 is the adjustment ring 110 that is a rotational ring type. When the selection ring 120 a is disposed behind the adjustment ring 110, the selection bar 74 is disposed under the adjustment bar 73 on the display screen.

In FIG. 7, the i-Function menu showing the selection bar 74 and the adjustment bar 73 is disposed in a lower end portion of the display screen 70. The selection bar 74 may be displayed on the selection region 72, such that display items are disposed in a horizontal direction from left to right or from right to left according to a set order. The adjustment bar 73 may be displayed on the adjustment region 71 in parallel with the selection bar 74. In this case, the selection bar 74 and the adjustment bar 73 may be displayed in an upper end portion or a lower end portion of the display screen 70.

In FIG. 13, an i-Function menu showing the adjustment bar 33 and the selection bar 34 is disposed on the right side of a display screen 30.

The selection bar 34 may be disposed on a selection region 32 such that display items are disposed in a vertical direction from top to bottom or from bottom to top according to a set order. The adjustment bar 33 may be displayed on an adjustment region 31 in parallel with the selection bar 34. In this case, the selection bar 34 and the adjustment bar 33 may be displayed in a left end portion or a right end portion of the display screen 30.

When the i-Function menu is disposed in a vertical direction, the adjustment unit 110 may be the adjustment ring 110 a which is slid in the longitudinal direction of the lens barrel 100 a. In this case, the adjustment ring 110 a moving forward or backward and the adjustment bar 33 adjusted in the vertical direction are disposed in the same direction, such that the user can intuitively connect the PUI and the GUI.

A control method for an apparatus for processing a digital image according to another embodiment is a control method for the digital image processing apparatus 10 described with reference to FIGS. 1 through 13. Thus, the description referring to FIGS. 1 through 13 can also be applied to the control method in the same manner.

The control method may include an image input operation, an image display operation, a selection region display operation, and an adjustment region display operation.

In the image input operation, an input image is inputted. In the image display operation, the input image is displayed on the display screen 70 or 80.
